It’s fine to search through random results for an outcome you’re aiming for. Just don’t call it Darwinian evolution.
This finding fits Michael Behe’s book Darwin Devolves perfectly. It’s easier to throw cargo overboard than to create it.
We looked at some papers claiming to see evolution happening in real time, to see if natural selection has actually invented a new function, or just broke an existing function.
Watch how easy it is to tell a Darwinian story. If something exists and looks advantageous, it evolved.
If life didn’t depend on these acts by cellular organelles and molecules, we would consider them death-defying performances in the greatest show on earth.
